CLEVELAND PINKNEY, OF GEORGETOWN, SOUTH CAROLINA.

SMOKERS' PIPE.

Application filed April 6, 1917.

Th all whom it may cancer-n Be it known that I, CLEVELAND PINKNEY, acitizen of the United States, residing at Georgetown, in the county ofGeorgetown and State of South Carolina, have invented new and usefulImprovements in Smokers Pipes, of which the following is aspecificat-ion.

This invention comprehends improvements in smokers pipes, and relatesmore particularly to that class of pipe known as bottom draft, whereinthe bowl is provided with a chamber extending entirely therethrough fromtop to bottom and open at each end.

()ne of the objects of the invention is to provide a pipe of thisnature, which in spite of its peculiar construction is not clumsy, andwhich possesses the same general appearance as pipes of the common type.

Another and more specific object of the invention resides in theprovision of a bottom draft pipe having a smoke passage communicatingwith the tobacco chamber at a point adjacent the top thereof andcommunicating with the stem passage below the tobacco chamber.

Another and more specific object of the invention is to provide a pipehaving a stem opening into the bowl below the tobacco chamber and havingits inner end closed by a valve, which may be easily opened to permit ofthe stem being cleaned either by running Water therethrough or by acleaner in the usual manner.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthand falling within the scope of the claims.

In the accompanying drawings Figure 1 is a side elevation of the pipe.

Fig. 2 is a longitudinal sectional view of the pipe.

Fig. 3 is a fragmentary detail view showing the construction of theupper end of the smoke passage leading from the tobacco chamber.

Referring in detail to the drawings by numerals, 1 designates the bowlof the pipe, which may be made in any desired shape, and which is formedwith a chamber extending entirely therethrough. The upper portion 2 ofthe bowl chamber forms a tobacco receiving compartment, which isprovided at its lower end with a concavo-convex grate Specification ofLetters Patent.

3 perforated in any desired manner. The grate rests upon a shoulder 4formed by contracting the passage through the bowl at its lower end.

Extending longitudinally through thewall of the bowl parallel to thecentral passage thereof is a smoke flue or passage 5, communicating atits upper end withthe tobacco chamber through the medium of a notch 6,and at its lower end with a smoke passage 7 in the stem 8. A mouth-piece9 isthreaded into the stem 8.

The inner end of the smoke passage 7, which opens into the bowl belowthe tobacco chamber is normally closed bya valve. 10 threaded upon thevalve rod 11, said rod entending through the wall of the bowl inalinement with the passage 7 and being provided'upon its outer end witha button 12. An expansive helical spring 13 encircles the rod 11 andholds the valve 10 closed when the pipe is being used. 7

A Cover 14 is hinged, as at 15', to a band 16 surrounding the to of thebowl. Thi band is locked in position ,by a depending flange 17 whichfits into the vroove in the outer face of the bowl. A clamping wire orring 18 may be used to secure the flange within the groove if desired.The cover is held closed by a latch 19, but may be easily swung openwhen desired by means of a lift 20.

Special importance is attached to the arrangement of the valve closingthe flue 7, and it is to be noted that when opened a straight passage isprovided through which water or a cleaner may be passed to removeaccumulations from the stem. It is important for sanitary reasons andessential to the perfect complete enjoyment of a smoke that the stem bekept clean, and this can only be accomplished when means are providedsuch as shown for running a straight instrument entirely therethrough.

From the foregoing description, taken in connection with theaccompanying drawings, it will be apparent that I have provided a verysimple, practical, and attractive bottom draft pipe, having a valveclosedstem which may be easily and quickly cleaned when the valve isopened.

While I have shown and described the preferred embodiment of myinvention by way of illustration, it will be understood that minorchanges in the construction and y bowl formed with a straight smokepassage oipening into'one side of said cavity,a valve s ldably extendedthrough the side ofsaid bowl opposite said stem and having a head withinsaid cavity, and resilient means normally forcing said head against theside of .Said bowl-to close "the end ofsaid smoke passage; said bowlformed with an opening below the inner end ofsaid smoke passage,

a d further formed with a passage having one end openin into said'cavityat a point distinct from t e. first mentioned passage and" having theother end opening into the first mentioned passage intermediately-of itsends; and means whereby when said valve is closed the smoke will passthrough the sec- 0nd mentioned passage.

2.1111 assmokers pipe, a bowl having a central chamber extendingentirely therethrough and open at eachend, a grate positioned,within-said chamber forming in the upper end thereof a tobaccocompartment, a stem havin' a straight smoke passage opening into t ebowl below the grate, the bowl being formed with a passage communicatingwith the passage in the stem and with the tobacco compartment adjacentits upper end, and a valve mounted within the lower end'of the bowlpassage for movement toward and away from the stem to normally close theinner end of the smoke passage through the Stem. v

3. A smokers pipe including a bowl having a central passage extendingtherethrough and open at each "end, a grate mounted within such passageforming the upper end thereof a tobacco compartment, a stem extendingfrom the bowl below the grate and valve, and a cover mounted on theupper end of the bowl, said. valve when opened estab lishing straightpassage from the bowl through the pipe stem.

In testimony whereof I allix my signature;
